ABSTRACT:
The hydrocyclone is provided with a hollow rotor which is constructed in the form of a radial pump rotor and the outlet orifice of the rotor is disposed in a casing having a tangential outlet aperture. The bend in the rotor produces an increase in pressure during use so as to compensate for any pressure losses as well as to allow the use of a feed pump of low-pressure capacity. A disc is also mounted on the rotor in place of a seal to prevent heavy particles from entering the upper casing.
